Given: ΔАВС, m∠ACB = 90°

Question

m∠ACD = 30°
AD = 8 cm.
Find: CD, Perimeter of ΔABC

plz add answer

Answer 1

I assume D is on AB?
Is it an altitude hitting AB at 90deg ?

if so A is 60 and B is 30

then CD = 8 sqrt 3

AC = 16
AB = 32
BC = 16 sqrt 3
so perimeter = 48 + 16sqrt3

Answer 2

yOu ugly trassh the answer is 12
